Understanding Livewire Protocol

Livewire is a digital audio networking protocol developed by Axia Audio, a division of Telos Alliance, specifically for professional Broadcast and live sound applications. It operates over standard Gigabit Ethernet networks using Internet Protocol (IP) transports, allowing multiple audio channels - along with control data and metadata - to coexist on a single network cable.

The systems also supports GPIO routing over IP, enabling automation of muting, console selection, and emergency alert systems with out additional cabling.

Role in Live Sound Reinforcement Systems

W live sound context, Livewire functions as te digital backbone that connects thee front-of- housie (FOH) console, monitor console, stage boxes, amplifies, and processing acks. Instad of running multiple long cables from thee stage to FOH, a single Ethernet cable - or a sumplant pair - carries all audio direnedireconally. Thi drastically reduces cable walt, setup time, and thee potentional for ground loops our magnetic interference.

System Architecture andTopology

A typical Livewire- based live sound system consiges several key consigents:

  • Livewire Nodes: Tese interface devices convert analogi or digital audio into Livewire IP streams. Stage boxe wigh multiple inputs andd outputs connect microphone andd line- level sources to te network.
  • Przełączniki Network: Managed Gigabit Ethernet changes with support for IGMP snooping, QoS, and AVB capabilities are required to handle multicast traffic and maintain low latency.
  • Consoles: Axia consoles (np., Element, Fusion, Radius) are nativie Livewire devices, but any AES67- compatible ble console can participate in the network.
  • Amplifiers andProcessors: Many modern powild loudspeakers andDSP units include Livewire or AES67 network interface, enabling digital connection from the console.

Te topologiczne can a star, ring, or daisy chain, depending on physical layout and reduncy requirements. In touring applications, a sumplant ring topology is contrign, where two fiber or copper paths connect all nodes, ensuring that a single failure does not interrupt audio.

Signal Flow andRouting

Audio routing in Livewire is complished via multicaste IP streams. Each audio channel is assigned to a multicastle additional hardware. For example, a lead vocal microphone can by sent to FOH, monitors, broadcast truck, and recordg rig alal at once, each with ent gain anand processing ided.

Te ruting can be changed in real time through gh companiere, making it possible te o reconfigurate thee entire system between acts or even during a performance without out repatching cables. This emplibility is invaluable in festivals and multi- act events where different configurations are required quicly.

Advantages Over Traditional Methods

While Livewire simplifies many aspects of system design, succecceful deployment requires careful planning and adsirence te o networking bett practices. The following guidelines help ensure stable, high-performance operation in live sound environments.

Network Design andSwitching

Usie managed changes with full support for IGMP snooping, which ensures that multicaste audio streams are only forwarded to ports that need them, preventing unnecessary bandwidt consumption. Enable Quality of Service (QoS) to prioritize audio traffic over tear data, using IEE 802.1p priority tagging. Consider using separate Vlans for audio and controil traffic to istate Broadcast and reduce congestion.

For larger networks, implement a sumplant topology such as a ring wigh RSTP, or use Livewire 's commanditary redumant stream faciure. Ensure that changes have equilent backplane capacity to o handle te e aggregate bandwidth of all audio streams with out dropping packets.

Clocking andSynchronization

All devices in a Livewire network mutt share a color clock reference te to prevent sampe mismatches ande audio artifacts. Livewire use the Precision Time Protocol (PTP) as dedicated IEE 802.1AS, with one device acting as the grandmaster clock. In live sound systems, the FOH console or a dedisated PTP granmaster should be use. Ensure that all changes are PTTT -aware or aid aid ast ast transparent o PTP traffic.

Cabling andInfrastructure
